.SH NAME
blind - Collection of command line video editing utilities
.SH DESCRIPTION
.B blind
is a collection of command line video editing utilities.
.B blind
uses a custom raw video format with a simple container.
If you have a video file you want to edit, you first
have to convert it with
.BR blind-from-video (1).
To be able to play your video in a video play, you
have to convert it with
.BR blind-to-video (1).
.P
Raw video takes up tremendous amount of space, you
should therefore avoid storing the video without
first convert it with
.BR blind-to-video (1).
